COLUMBUS, Ohio (WCMH) -- While the Buckeyes are getting back a star offensive lineman for its noon kickoff against Marshall, they will be without a star defensive lineman. The Scarlet & Grey are concluding nonconference regular season play Saturday against the Thundering Herd in Columbus and have a mostly empty injury report. Left guard Donovan Jackson is available and will start his first game of the season while starting defensive tackle Tyleik Williams is one of three players unavailable for Saturday's game. The senior from Virginia played in the opening two games of the season, recording nine tackles and 1.5 sacks. Three things to watch when Ohio State hosts Marshall on Saturday Ohio State injury report (Week 4 vs. Marshall) OUT RB TC Caffey (Out for season) RB Rashid SeSay DT Tyleik Williams The third-ranked Buckeyes are looking to complete its three games before Big Ten play with a sweep of routs as they enter Saturday as more than five-touchdown favorites against Marshall. Both teams enter well rested after bye weeks so Ohio State's offense could come out faster than it did in its last game against Western Michigan. Marshall is 1-1 with a 45-3 win over Stony Brook and a 31-14 loss to Virginia Tech. The Sun Belt side will return to Huntington, West Virginia next week when they host Western Michigan.
